When using the Scissors effect as shown below, I’m still observing the same behavior that it doesn’t apply the effect successfully unless I’m in the middle of the voxel of the foreground volume which is my master volume for the segmentation. For slice cut “0 means that only the current slice is included.” I would expect this to work regardless of the volume’s slice thickness. It appears that it will fill only if I set the slice thickness to a value so that it will cross over the middle position of the voxel. This is because the required minimum slice thickness to fill increases the farther I’m away from the voxel center.
When I scroll to another slice offset (note the background volume is a finer resolution), then I cannot use the scissors tool anymore to modify the segment. The yellow scissors free-form disappears, but nothing changes about the segment.
